Raster Imaging System Structure(IM:XP)

Raster Imaging System Structure
The raster imaging system structure, of data type gxRasterImageDataRec, is the structure that QuickDraw GX uses to maintain information about the state of the raster imaging system. This structure is used with the GXRasterLineFeed and GXRasterPackageBitmap messages, which are described in the section
"Raster Imaging Messages" beginning on page 4-97.

Field Description

renderOptions
Rendering options for raster imaging. This value is the combined values of the constants that you include from the raster render options enumeration, which is described in the next section.
hImageRes
The horizontal resolution for imaging.
vImageRes
The vertical resolution for imaging.
minBandSize
The minimum band size to use, in pixels.
maxBandSize
The maximum band size to use, in pixels.
pageSize
The size of the page in pixels.
currentYPos
The current position on the page.
packagingInfo
The raster package structure.
optionsValid
A Boolean value that is true if options are specified for the packaging messages and false if not.
packageControls

The raster package controls structure.
theSetup
The setup for the offscreen planar area data. This is a variable length object.
